I think what stands out most about this game, beyond its storyline or gameplay, is its art design.
The bizarre style of the Foundation and the superpower shooting—everyone must have played quite a bit of those, but such an intriguing, comprehensive architectural style, I've never experienced in a game before.
It integrates designs from many famous architects, such as Tadao Ando's Church of Light and the waffle grid, though I won't go listing dishes or mentioning those big names here.
The prototype of this game is based in reality: America's Long Line Building, a concrete fortress without any windows standing tall in the city.
After reviewing the related art analysis, I relied on my instincts to describe it in easily understandable terms: vast, strange, cold gray, authoritative, concrete, and more concrete, darn it.
Just kidding, this stuff is pretty complex, and my understanding is rather superficial, so interested readers can delve into it themselves.
